As rier with nib and feeder inproper association 55 ordinarily constructed, it is a rather messy opmaybe quickly applied. To facilitate removal and replacement, thedetachable shell may have aknurled flange 1.

The feeder member may be of any approved type, and it may be inclampedrelation with respect to the pen nib before the latter is inserted inthe carrier; the pen nib shown in Figs. 4 and 5 having wings 2* arrangedto embrace the body of the feeder which may be recessed for such purposeas indicated at 3*. It will be understood, of course, that thearrangement of pen and feeder illustrated in Fig. 4 wherein the pen isshown as provided with wings clamping the feeder, may be employed in theform of carrier illustrated in Figs; 1 and 2.

The carrier 1 has a rear wall 1" against which the feeder may abut; suchwall having a curved slot 1, to register with the ink groove 3", and thedimensions of such slot may be such as to enable easy assembly of theparts with a fully open passage for the ink.

The connection between the carrier 1 and the pen barrel or the tubularcap B at the end of the pen barrel, may be of any suitable type withinthe range of fountain pen construction. It may be a threaded joint asindicated in Figs. 1 and 2, with one or a plurality of continuous, orinterrupted, threads, or it may be a slip joint as shown in Figs. 4 and5. Any form of connection that will insure the desired liquid tightclosure between the inserted or applied part carrying the nib and feederand the tubular cap carrying the ink bag is within the scope of myinvention.

As may be readily understood, several of my improved nib carriers may besold with a fountain pen of a construction designed to receive the sameas articles of merchandise; similar carriers with any desired form ofpen nib being also sold for application thereto, so as to providereplacements for the original structure.

While I have illustrated fountain pens of the type having collapsibleink bags which may be filled automatically upon retraction of collapsingmeans, I do not wish to be limited thereto and other forms of fountainpens, among which may be mentioned those filled by suction by the actionof a piston member, may be equipped with the unit nib and feedercarrying member forming the subject of my invention.

It is, of course, within the scope of my invention to employ gold nibsin connection with the unit member I have devised, and the claims areintended to cover unit members for connection with the barrel offountain pens containing ink supplying means, whether such nibs are ofsteel or of any other metal. In like manner, the feeder element may beof any type that will properly perform its function. It may be entirelydifferent from the form of feeder disclosed, which representation ismore or less diagrammatic and is intended to indicate means forperforming a function rather than the member that will be actuallyemployed for such purpose.
